The invention relates more particularly to means for closing and protecting the ends of rolled material such as roofing 'paper,"etc.`

I andto 'a method for vattaching suclrvmeans. f n In shipping material ofjthis type, Vit is customary vto place within the bore' ofv the' roll anu'mber kof packages 'containing' nails,l washers, cement, etc., andto provide incombination withffa pair of f dished end plates whichserve toprotect 4the ends of the roll, a tying'meansfor securing'the endplates and' packages'to 'the roll. 'p v' .lhis tyingmeans hasgenerally taken the form ofV a'rod head- .ed at one en dpand provided with a clamping niit'threaded von the other end, or merely a y wire or rod inserted throughV central Yapertures in the end platesand bent over at its ends. `.Itis evident Vthat tie" rods Vhaving threaded portions are weaker at ,the threaded part of the rod and must therefore be made of a relatively larger cross'v section in order* to provide'fthe" necessary"y tensile Astrength efectivelyto clamp'the closures to theroll.1 Considering the 'manythousands of such vrods' usedlyaA slightfsaving'in the weight: of each createsan appreciable sav-y ing not l, only 1in :the 'cost of material but also yin freight-,costs VVVitlrthe ,wire typedef rod A* bent over at its ends,y it is kapparent that yto attach theclosures with such a rodV under f tension, would requirea cumbersome operation and could provideno greater tension thanv that which the rod.` f l It is the ygeneral-'object of the invention to provide a ,new andiinproved end closure i andftie rod construction for hollow@ rolls,- economicalv of materiali and manufacture, readily attached, `andy rugged and effective in use; y f

Another objectisto provide anli'mproved end construction embodying a pair 'of 'closures and' a tie rod formed of stock of uni-v form Section having deformed orV upset portions arranged to clamp the' closures on roll with the rod' under' tension'.l y y In pursuance ofthe foregoingjobjects, we aim tofprovidea 'pair of 'thin dishedk disks having "central `apertures ltherein together with lwashers positioned against the outer Wouldtend to re-stra'ighten l u v' e and alternative"constructionsvfalllng within sides `of the disks t'o reinforce them and ai tie rod arranged ftoclampv the closures thusk formed to the opposite endsof a roll. and

Figs. 3to`5 disclose a manually operable upset and cut of'fthe tie rod during the process of attaching the olosuresto a roll: Inasmuch as this tool is not'claimed in this application',

it will-be described but generally. l The tool an end disk .5fL withfa pair of upsetting'jaws: 13,` 14, Vabutting the washer V6? and arranged to is shown in position against4 upsetthe tie rod 7y immediately adjacent gthe'washer aty 12 and'has a shear blade 15 Y Y 'Y has been formed.

These rolls are preferably driven simultaneously and 1n opposite directions by intermeshing .pinions 195 20 and maybe actuated .by means includingi handle 21 mounted on one end of a shaft 21 which when operated in one direction Y actuatesthe rolls'to draw the rod outwardlyy of thel roll. A suitable ratchet device' (not showniis providedVV intermediate the shaft 21a and the rolls so thatwhen the shaft isV ,rotated in they opposite direction the rolls arev held against reverse rotation to maintain the rod under tension. j Y `The roll 18 is preferabiycorrugated and the roll 17 vis provided with a fiat spot, 22

so as to permit the insertion ofthe rod therebetween. Upon a rotation of the rolls withV the corrugated roll turning in a counterclockwise direction (Fig.v 3) the rod is gripped betM/'eenthev two rolls and drawn.

It will outwardly from the washer 6%' Vthereby clamping theV end( closures against the Vends of the fabric roll with the upsetting jaws 13, 11i inV abutment with the washer `6a. The

mechanism of the device is such that upon the completion ofthe tensioning'operationV the handle 21 Vmay be rotated in the reverse direction to actuate the jaw 111 to upset'the 'Y rod and to actuate the shearjblade 15 to cut ol the rod. This mechanism is :herein shown asV compri-sing generally arms 23, 24,v connected respectively to `the jaw 111' and shear blade 15 which arms arek arranged to be actuated by cams 25, 26driven by means i of a worm 27and worm wheel 28* on the Y shaft Y 21a'.

lTo apply the device to a rollitis merely necessary to pass the tie vrod through.. one disk to a position wherein the washerk (ifL abuts the disk, thenr pass the rodthroughv the bore of-tbe roll and over the enclosed packages-and place a second diskV upon Vvthe.

extended portion ofthe rod. The disks may then.be Vpositioned centrally of .the kroll and, by means of a tool such as shown, thev rod may first be tensioned to clamp the disks and packages against the roll and thenupset and'V shearedoif to' retain ,the parts in that posi-f tion. Y

closed herein can .be cheaply vmanufactured from a wire or rodof uniform vsection and Y that because 'the operations performed upon the rod'for adapting-it toclamp-the end closures are arranged to providean effective clamping meansfwithout weakening theffrod, a rod of minimum crossy section may be used with washers positioned to reinforce.

lVe claim as ourinvention:

1. A protective means forpaper rolls having a central bore, comprisingin combinasaid bore and having its opposite ends pro'- jectingV through the apertures inthenplates with upset heads on said projectingends', and washers interposedbetween said heads andthe outer sides of said plates, said heads Y being positioned 'on the rod so as to'hold it under tension with the plates in .firm con? tact with the ends vof theV roll, and Vsaid rod further ha'vingan upset portionfspaced'inwardly from one of said headsand adaptedV to retain one of said washers between it and" the head before assembly of therrodin the roll. .Y j

tion a pair of apertured plates one for each A endfof'the roll, a rod extending through 2.v A protective means for papery rolls having a central bore, comprising in combina- K l. tion a pair of apertnred plates one for each end of the roll, a rod adapted to be passedk through the central bore of ,a roll With its opposite ends projecting through the apertures in said plates When'theY latter engage Withvthe ends of the roll, one of said pro*- jecting ends having means engaging with the plate to hold the rod against movement inwardly of the plate, and theV other projectng end portionv of thev rod beingfdeformed cross seetionally to .provide an abutment acting against the plate adjacent thereto to hold the road under tension.

In testimony whereof We havel hereunto affixed our signatures. l
